Someone has tried to parallelize Lennart&#39;s Haskell from my ray tracer language<br>
comparison and they are claiming awesome performance results for Haskell,<br>
even beating HLVM:<br>

Frankly, I don&#39;t believe their claims for a second. So I&#39;d like to test their<br>
code for myself. However, apparently their code needs some third-party<br>
library that can be installed with:<br>
<br>
cabal install AC-Vector<br>
<br>
but, on my machine, that only seems to make the library accessible to GHC 6.10<br>
and not to GHC 6.12 (which is needed to compile this benchmark).<br>
<br>
What is the easiest way for me to get this library working under GHC 6.12?<br>
